Orthogonal wavelet division multiplex as a modulation scheme for digital television

Issues surrounding wireless communications have arisen as a result of an increase in popularity and usability. The complexity of modulating signals over carriers is considered to be a significant challenge and Orthogonal Frequency Division Multiplex has proven to be a popular technology. The discovery of the wavelet transform, while mainly used in image processing applications, has led to a recently proposed, innovative new modulation technique called Orthogonal Wavelet Division Multiplex. This paper looks at the application of different families of wavelet as applied to digital terrestrial television.
